I got finally a text message from a real number 647 461-5674 as they could not get me on phone. They use system that generate fake number on screen when they call you. I am going to make complaint against this number to CRTC
This number has called me for days. When I answer and get a prerecorded message about a business website that wants to take care of renting my apartment, I hang up. They then continued to call back until I listened to the whole message and choose a number from a menu to be removed from their list. They got my number from a newspaper ad I put in the classifieds.
